Description

Technical Field

[0001] The present invention relates to the technical field of high-purity semiconductor material processing, and in particular to an automatic feeding device of a jaw crusher and grinder integrated machine. Background Art

[0002] Wafer crushing is a key step in waste recycling in semiconductor manufacturing, requiring high cleanliness, low contamination, and precise particle size control. By combining the coarse crushing capabilities of a jaw crusher with the fine grinding functions, the jaw crusher-grinder specifically addresses the high hardness, high brittleness, and low contamination requirements of silicon wafers (monocrystalline silicon).

[0003] In related technologies, the jaw crusher and grinder first uses the jaw crusher coarse crushing unit to crush the wafers. Through the traditional jaw crusher's movable jaw and fixed jaw extrusion mode, the extrusion force is controlled by a high-precision hydraulic system to adapt to the physical properties of single crystal silicon (Mohs hardness 7). The crushed wafers are then ground using the grinding and fine crushing unit to further refine the wafer fragments to 0.1 to 1 mm, thereby meeting the requirements for silicon material recovery.

[0004] A Chinese patent with authorization announcement number CN103406188B discloses a fully automatic crushing and grinding machine, which includes: a crusher, a grinder and a conveying system. The grinder is connected to the crusher, the crusher includes a crusher feed port, the grinder includes a grinder discharge port, the conveying device includes two, and the two conveying devices are respectively arranged at the crusher feed port and the grinder discharge port. The conveying system includes a conveying device for conveying samples and a sample conveying pipe.

[0005] The above-mentioned fully automatic crushing and grinding machine sends the material to be processed into the crusher through the conveying device. After the sample is crushed, it enters the grinder through the sample conveying pipe. The ground sample is output through the conveying device, thereby making the entire process of sample crushing, grinding and conveying mechanized, without the need for manual transfer operations, greatly reducing the workload of sample crushing and grinding.

[0006] However, due to the large size of wafers, when feeding the wafers into the crusher feed port, since the wafers are circular plate-shaped structures, directly dumping the wafers into the crusher feed port can easily cause the wafers to accumulate in the hopper of the feed port, thereby causing a jamming phenomenon. The crusher feed port of the jaw crusher and grinder is usually located at the top of the equipment, which makes it difficult for staff to handle and affects work efficiency. Summary of the Invention

[0007] The present invention provides an automatic feeding device for a jaw crusher and grinder, aiming to solve the problem in the related art that wafers are easily stuck when they are directly poured into the crusher feed port.

[0008] The automatic feeding device of the jaw crusher and grinder integrated machine of the present invention includes: a storage bin, a workbench, a lifting mechanism, a transverse movement mechanism, a rotation mechanism, a first interference mechanism, and a second interference mechanism; The storage bin is arranged on the workbench. The lifting mechanism is used to drive the workbench to move up and down. The transverse movement mechanism is used to drive the workbench to move horizontally. The rotation mechanism is used to drive the workbench to rotate; The first interference mechanism includes a fixed rod, a sliding rod, and a rotating rod. The fixed rod is arranged on the workbench and beside the storage bin. The sliding rod is slidably fitted on the fixed rod. The rotating rod is rotatably fitted on the sliding rod. The second interference mechanism has the same structure as the first interference mechanism and is symmetrically distributed on the other side of the storage bin. After the workbench is turned over, the two rotating rods can carry the wafers and push the sliding rods to move under the action of the gravity of the wafers, so that the two rotating rods are both abutted against the side wall of the feeding hopper of the jaw crusher and grinder integrated machine, realizing that the wafers are parallel to the side wall of the feeding hopper.

[0009] Beneficial effects: Multiple wafers are stacked up and down in the storage bin manually. Then, the storage bin is moved above the feeding hopper of the jaw crusher and grinder integrated machine through the lifting mechanism and the transverse movement mechanism. Then, the rotation mechanism turns the workbench 180 degrees. The storage bin rotates synchronously with the workbench, so that the wafers in the storage bin fall downward under the action of gravity. During the falling process, the two ends of the wafers are abutted against the rotating rods on the first interference mechanism and the second interference mechanism, and the rotating rods drive the sliding rods in the first interference mechanism and the second interference mechanism to slide downward until the rotating rods of the first interference mechanism and the second interference mechanism are both above the side wall of the feeding hopper of the jaw crusher and grinder integrated machine. The vertical distances between the two rotating rods and the side wall of the feeding hopper are equal. The vertical distance between the two rotating rods and the side wall of the feeding hopper is greater than the thickness of one wafer and less than the sum of the thicknesses of two wafers. The rotating rods support the wafers, so that the wafers are parallel to the side wall of the feeding hopper. Then, the rotating rods rotate, so that the wafers can fall on the side wall of the feeding hopper and slide into the feeding port in sequence, thus avoiding multiple wafers sliding into the feeding port at the same time, further avoiding the wafers piling up at the feeding port, and preventing the wafers from blocking the feeding port.

[0010] Preferably, the rotating rod is connected to the sliding rod through a torsion spring. A receiving groove is arranged on the sliding rod, and the rotating rod can be placed in the receiving groove.

[0011] The effect is that by arranging the receiving groove, when loading the wafers into the storage bin, the rotating rod can be received into the receiving groove, thus avoiding the rotating rod from hindering the wafers from entering the storage bin and facilitating the feeding.

[0012] Preferably, a locking mechanism is further provided. The locking mechanism includes a limiting plate, a pushing block, and a limiting unit. The pushing block is slidably fitted to the bottom of the fixed rod, one end of which is an inclined surface end, and the inclined surface end of the pushing block can extend into the storage bin. A sliding groove is provided on the sliding rod, the limiting plate is slidably fitted in the sliding groove and is connected to the sliding rod through a first elastic member. A slider is provided at the bottom end of the limiting plate, a V-shaped groove is provided on the pushing block, and the slider can extend into the V-shaped groove. A limiting unit is provided on the limiting plate, and the limiting unit can be clamped with the rotating rod.

[0013] The effect is that by clamping the limiting unit with the rotating rod, the rotation of the rotating rod can be restricted. When the storage bin is loaded with wafers, the wafers in the storage bin can push the pushing block to move outwards. The outward movement of the pushing block causes the slider to move along the V-shaped groove, thereby driving the limiting plate away from the rotating rod, thus releasing the limitation of the rotating rod. The rotating rod can rotate relative to the sliding rod, thereby avoiding the rotating rod from obstructing the wafers from entering the storage bin when loading wafers into the storage bin. When the workbench is flipped, the sliding rod extends out of the fixed rod, so that the slider is separated from the pushing block. Under the action of the first elastic member, the limiting plate can be in close contact with the rotating rod and is clamped with the rotating rod through the limiting unit, thereby limiting the rotating rod, so that the rotating rod can support the falling wafers after the storage bin is flipped.

[0014] Preferably, an unlocking groove is provided on the fixed rod, the top end of the unlocking groove is of an inclined surface structure, an unlocking plate is provided at the bottom end of the limiting plate, and the unlocking plate can extend into the unlocking groove. The limiting plate is elastically connected to the sliding rod.

[0015] The effect is that after the workbench is flipped, the sliding rod extends out of the fixed rod and gradually approaches the side wall of the feed hopper of the jaw crusher and grinding machine. During this process, the unlocking plate gradually approaches the inclined surface end of the unlocking groove. When the sliding rod is about to stop moving, the unlocking plate moves along the inclined surface of the inclined surface end of the unlocking groove, thereby pushing the limiting plate away from the rotating rod. When the sliding rod stops moving, the limiting plate is completely separated from the rotating rod, thus releasing the limitation of the rotating rod, so that the rotating rod can rotate. Under the action of the gravity of the wafers, the rotating rod rotates, so that the wafers can fall on the side wall of the feed hopper of the jaw crusher and grinding machine, avoiding the rotating rod from obstructing the wafers from falling on the side wall of the feed hopper.

[0016] Preferably, the limiting unit includes a limiting disk and limiting grooves. The limiting disk is provided on the sliding rod, and a plurality of the limiting grooves are circumferentially and spacedly distributed on the limiting disk. A plurality of clamping blocks are provided on the rotating rod and are circumferentially and spacedly distributed along the circumference. The clamping blocks can extend into the limiting grooves, thereby realizing the clamping connection between the rotating rod and the sliding rod.

[0017] The effect is that by setting a plurality of limiting grooves, each clamping block on the rotating rod can extend into the corresponding limiting groove, so that the rotating rod is clamped with the limiting plate. Even if a certain limiting groove loses its limiting ability due to wear, it can avoid the overall loss of the limiting ability of the limiting unit, ensure the limiting ability of the limiting unit, and avoid the failure of the limiting unit.

[0018] Preferably, the limiting groove has an inclined surface end, and the limiting groove can limit the rotating rod unidirectionally.

[0019] Preferably, a bearing plate is slidably fitted in the storage bin, and the bearing plate is connected to the storage bin through a second elastic member.

[0020] Preferably, the rotating mechanism includes a rotating seat and a rotating cylinder. The rotating cylinder is arranged on the rotating seat, and the output end of the rotating cylinder is connected to the workbench. The rotating cylinder is used to drive the workbench to rotate.

[0021] Preferably, the transverse movement mechanism includes a sliding table and a first cylinder. The first cylinder is arranged on the sliding table, and the rotating seat is slidably fitted on the sliding table. The first cylinder is used to drive the rotating seat to move along the sliding table.

[0022] Preferably, the lifting mechanism includes a second cylinder and a connecting block. The connecting block is slidably fitted on the second cylinder. The second cylinder is used to push the connecting block to move up and down, and the sliding table is connected to the connecting block.

[0023] Adopting the above technical solutions, the beneficial effects of the present invention are as follows: According to the automatic feeding device of the jaw crusher and grinder integrated machine of the present invention, a plurality of wafers are stacked up and down in the storage bin manually, and then the storage bin is moved above the feed hopper of the jaw crusher and grinder integrated machine through the lifting mechanism and the transverse movement mechanism. Then the rotating mechanism flips the workbench 180 degrees, and the storage bin rotates synchronously with the workbench, so that the wafers in the storage bin fall downward under the action of gravity. During the falling process, the two ends of the wafers abut against the rotating rods on the first interference mechanism and the second interference mechanism, and drive the sliding rods in the first interference mechanism and the second interference mechanism to slide downward through the rotating rods until the rotating rods of the first interference mechanism and the second interference mechanism are both above the side wall of the feed hopper of the jaw crusher and grinder integrated machine. The vertical distances between the two rotating rods and the side wall of the feed hopper are equal, and the vertical distances between the two rotating rods and the side wall of the feed hopper are greater than the thickness of one wafer and less than the sum of the thicknesses of two wafers. The rotating rods support the wafers, so that the wafers are parallel to the side wall of the feed hopper. Then the rotating rods rotate, so that the wafers can fall on the side wall of the feed hopper and slide into the feed port in sequence, thus avoiding a plurality of wafers sliding towards the feed port at the same time, further avoiding the accumulation of wafers at the feed port, and preventing the wafers from blocking the feed port.

[0039] The transverse movement mechanism includes a slide table 4 and a first cylinder.

The slide table 4 is fixedly connected to the connecting block, and the second cylinder can drive the slide table 4 to move up and down through the connecting block.

[0041] As Figures 1 to 3 shown, the storage bin 1 is a cylindrical structure. The storage bin 1 is fixedly arranged on the workbench 2. The inner diameter of the storage bin 1 is larger than the diameter of the wafer. A carrier plate 71 is slidably fitted inside the storage bin 1. The carrier plate 71 is a circular plate structure. A second elastic member 72 is provided between the carrier plate 71 and the storage bin 1. The second elastic member 72 is a spring. One end of the second elastic member 72 is fixedly connected to the bottom end of the carrier plate 71, and the other end thereof is fixedly connected to the bottom surface of the storage bin 1. The carrier plate 71 can move up and down inside the storage bin 1.

[0042] As Figures 2 to 4As shown in the figure, the first intervention mechanism 5 includes a fixed rod 51, a sliding rod 52, and a rotating rod 53. The fixed rod 51 is a straight rod. The fixed rod 51 is arranged beside the storage bin 1. The bottom end of the fixed rod 51 is fixedly connected to the workbench 2. A mating groove extending along its length direction is provided on the fixed rod 51. The sliding rod 52 is slidably fitted in the mating groove and can extend out or retract into the mating groove. A guiding groove is also provided on the side wall of the mating groove. A limiting protrusion is provided on the side wall of the sliding rod 52. The limiting protrusion is slidably fitted in the guiding groove. The provision of the guiding groove can prevent the sliding rod 52 from deflecting when it extends out of the mating groove. A third elastic member 521 is further provided between the sliding rod 52 and the fixed rod 51. The third elastic member 521 is a spring. One end of the third elastic member 521 is fixedly connected to the bottom end of the limiting protrusion, and the other end thereof is fixedly connected to the bottom surface of the mating groove.

[0043] As Figure 4 and Figure 5 shown in the figure, a receiving groove 522 is provided at the top end of the sliding rod 52. The rotating rod 53 is slidably fitted at the top end of the receiving groove 522 through a rotating shaft. The rotating rod 53 can rotate relative to the sliding rod 52 around the rotating shaft. The rotating shaft is rotatably connected to the sliding rod 52 through a torsion spring. The rotating rod 53 can be received in the receiving groove 522. When the torsion spring is in a natural state, the rotating rod 53 and the sliding rod 52 are vertically distributed. The bottom of the receiving groove 522 is an arc structure, and its radian is the same as the rotation range of the end of the rotating rod 53, so as to avoid the rotating rod 53 colliding with the sliding rod 52 when rotating.

[0044] As Figures 3 to 9As shown, a locking mechanism is further provided on the sliding rod 52. The locking mechanism includes a limiting plate 541, a pushing block 542 and a limiting unit. A sliding groove 523 is provided on the sliding rod 52. The sliding groove 523 is located beside the storage groove 522 and communicates with the storage groove 522. The sliding groove 523 penetrates through the top and bottom ends of the sliding rod 52. The limiting plate 541 is slidably fitted in the sliding groove 523 and is elastically connected to the sliding rod 52 through a first elastic member 5411. The first elastic member 5411 is a spring. One end of the first elastic member 5411 is fixedly connected to the limiting plate 541, and the other end of the first elastic member 5411 is fixedly connected to the sliding rod 52. The limiting plate 541 can approach or move away from the rotating rod 53. The first elastic member 5411 is always in a compressed state, so as to always apply a force towards the rotating rod 53 to the limiting plate 541. A fitting hole is further provided on the limiting plate 541. The limiting plate 541 is slidably fitted with the rotating shaft through the fitting hole. The pushing block 542 is slidably fitted on the bottom surface of the fixed rod 51. One end of the pushing block 542 is an inclined surface end. An opening is provided on the side wall of the storage bin 1. The inclined surface end of the pushing block 542 can extend into the storage bin 1 through the opening on the side wall of the storage bin 1. A V-shaped groove 5421 is provided on the top surface of the pushing block 542. A sliding block 5412 is fixedly provided at the bottom end of the limiting plate 541. The sliding block 5412 can extend into the V-shaped groove 5421 and can slide along the V-shaped groove 5421. The pushing block 542 is elastically connected to the fixed rod 51 through a fourth elastic member. The fourth elastic member is a spring. One end of the fourth elastic member is fixedly connected to the pushing block 542, and the other end of the fourth elastic member is fixedly connected to the fixed rod 51. The fourth elastic member is always in a compressed state, so as to always apply a force towards the storage bin 1 to the pushing block 542, and further be able to push the pushing block 542 to extend into the storage bin 1 through the opening. An unlocking groove 511 is further provided on the positioning rod. The top end of the unlocking groove 511 is an inclined surface structure. An unlocking plate 544 is further fixedly provided at the bottom end of the limiting plate 541. One end of the unlocking plate 544 is fixedly connected to the limiting plate 541, and the other end of the unlocking plate 544 extends into the unlocking groove 511 and is in contact with the bottom of the unlocking groove 511. The unlocking plate 544 is slidably fitted with the unlocking groove 511 and can slide along the unlocking groove 511. A connecting block is further fixedly provided on the unlocking plate 544. The connecting block is elastically connected to the sliding rod 52 through a fifth elastic member. The fifth elastic member is a spring. One end of the fifth elastic member is fixedly connected to the connecting block, and the other end of the fifth elastic member is fixedly connected to the sliding rod 52.

[0045] In the initial state, the push block 542 extends into the storage bin 1 under the action of the fourth elastic member. The bottom end of the sliding rod 52 abuts against the top surface of the push block 542. The slider 5412 is located at the end of the V-shaped groove 5421. The first elastic member 5411 of the limit plate 541 abuts against the rotating rod 53, so that the limit unit can limit the rotation of the rotating rod 53, thereby preventing the rotating rod 53 from rotating away from the storage slot 522. When wafers are placed in the storage bin 1, the weight of the wafers pushes the supporting plate 71 downward. During the downward movement, the supporting plate 71 contacts the push block 542 and squeezes the push block 542, causing the push block 542 to move outward. During the outward movement of the push block 542, the slider 5412 moves within the V-shaped groove 5421. The slider 5412 can push the limit plate 541 away from the rotating rod 53, overcoming the elastic force of the first elastic member 5411 and disengaging from the rotating rod 53, thereby releasing the limit on the rotating rod 53. When the workbench 2 is flipped 180 degrees, the wafers in the storage bin 1 fall downward under the action of gravity and stop with the rotating rod 53. The wafers will push the rotating rod 53 to move downward, and the rotating rod 53 will drive the sliding rod 52 to move downward. During the downward movement of the sliding rod 52, the slider 5412 will disengage from the V-shaped groove 5421. When the slider 5412 is completely disengaged from the V-shaped groove 5421, the limit plate 541 gradually approaches the rotating rod 53 under the action of the stretching elastic force of the first elastic member 5411 until it stops with it, thereby restoring the limit on the rotating rod 53. When the unlocking plate 544 and the inclined surface end of the unlocking groove 511 are stopped, the inclined surface end of the unlocking groove 511 squeezes the unlocking plate 544, and causes the unlocking plate 544 to overcome the elastic force of the fifth elastic member and move toward the limiting plate 541, and drives the limiting plate 541 to overcome the elastic force of the first elastic member 5411 and move away from the rotating rod 53, thereby achieving the unlocking of the rotating rod 53.

[0046] like Figures 8 to 11As shown, the limiting unit includes a limiting plate 5431 and a limiting groove 5432. A circular groove is provided on the limiting plate 541, and the circular groove is coaxially distributed with the rotating shaft. The limiting plate 5431 slides in the circular groove and is elastically connected to the limiting plate 541 through a spring. A plurality of limiting grooves 5432 are evenly spaced along the circumference of the limiting plate 5431 on the limiting plate 5431. One side wall of the limiting groove 5432 is perpendicular to its groove bottom, and the other side wall has an obtuse angle with its groove bottom, thereby forming a bevel end. A plurality of clamping blocks 531 are provided on the rotating rod 53, and the plurality of clamping blocks 531 are evenly spaced along the circumferential direction. Each clamping block 531 corresponds to a limiting groove 5432. The clamping block 531 can extend into the limiting groove 5432, so that the rotating rod 53 and the limiting plate 5431 are clamped together, and can limit the rotating rod 53 to prevent the rotating rod 53 from rotating. Since there is an obtuse angle between one side wall of the limiting groove 5432 and the bottom surface of the limiting plate 5431, the limiting unit can only limit the rotating rod 53 in one direction.

[0047] The second intervention mechanism 6 has the same structure as the first intervention mechanism 5 , and the two are symmetrically distributed on both sides of the storage bin 1 . The length of the unlocking slot 511 on the fixed rod 51 in the second intervention mechanism 6 is smaller than the length of the unlocking slot 511 on the fixed rod 51 in the first intervention mechanism 5 .

[0048] The implementation principle of the automatic feeding device of the jaw crusher and grinder according to the embodiment of the present invention is as follows: The lifting mechanism in the automatic loading device 100 of the jaw crusher and grinder in the embodiment of the present invention is fixedly arranged on the outer wall of the shell of the jaw crusher and grinder. When loading is required, the lifting mechanism drives the slide 4 to move to the lowermost end of the second cylinder. The staff manually rotates the rotating rod 53, so that the rotating rod 53 overcomes the elastic force of the torsion spring and rotates until the rotating rod 53 is received in the receiving groove 522. During the rotation of the rotating rod 53, the blocking block 531 can move along the inclined end of the limiting groove 5432. When the rotating rod 53 is received in the receiving groove 522, the blocking block 531 extends into the limiting groove 5432. The limiting groove 5432 can prevent the rotating rod 53 from rebounding, thereby preventing the rotating rod 53 from affecting the loading. After multiple wafers are placed in the storage bin 1 in sequence, under the action of the gravity of the wafers, the supporting plate 71 overcomes the elastic force of the second elastic member 72 and moves downward. During the downward movement of the supporting plate 71, it will gradually approach the inclined end of the push block 542 until it stops with it and squeezes the push block 542, so that the push block 542 overcomes the elastic force of the fourth elastic member and moves outward. During the outward movement of the push block 542, the slider 5412 moves along the V-shaped groove 5421, so that the limit plate 541 overcomes the elastic force of the first elastic member 5411 and moves in the sliding groove 523, thereby moving away from the rotating rod 53, and then causing the blocking block 531 to disengage from the limiting groove 5432, releasing the limit on the rotating rod 53, and the rotating rod 53 rebounds to be perpendicular to the sliding rod 52 under the action of the torsion spring.

[0049] When the wafers in the storage bin 1 reach the designed number, the wafers are stopped from being put into the storage bin 1. The second cylinder pushes the slide 4 upward to the top, and then the first cylinder drives the rotating seat 3 to move horizontally, so that the rotating seat 3 moves to above the feed hopper of the jaw crusher and grinder. Then the rotating cylinder drives the workbench 2 to rotate 180 degrees clockwise, so that the workbench 2 is flipped, and the wafers fall downward under the action of gravity until the wafers stop with the rotating rod 53 in the first intervention mechanism 5 and the second intervention mechanism 6. The wafers push the rotating rod 53 to move downward, and the rotating rod 53 drives the sliding rod 52 to move downward. During the downward movement of the sliding rod 52, the slider 5412 will disengage from the V-groove 5421. When the slider 5412 is completely disengaged from the V-groove 5421, the limit plate 541 gradually approaches the rotating rod 53 under the action of the elastic force of the first elastic member 5411 until it stops with it, thereby restoring the limit on the rotating rod 53, so that the rotating rod 53 can provide support for the wafer and prevent the wafer from falling. As the sliding rod 52 moves downward, the unlocking plate 544 gradually approaches the inclined end of the unlocking groove 511. When the unlocking plate 544 stops contacting the inclined end of the unlocking groove 511, the vertical distance between the end of the sliding rod 52 in the first intervention mechanism 5 and the second intervention mechanism 6 and the side wall of the feed hopper of the jaw crusher and grinder is less than the sum of the thicknesses of the two wafers, so that the wafer can be parallel to the side wall of the feed hopper of the jaw crusher and grinder. At this time, the inclined end of the unlocking groove 511 can squeeze the unlocking plate 544, and make the unlocking plate 544 overcome the elastic force of the fifth elastic member and move toward the limit plate 541, thereby driving The limiting plate 541 overcomes the elastic force of the first elastic member 5411 and moves away from the rotating rod 53, thereby causing the limiting plate 5431 to disengage from the blocking block 531, thereby unlocking the rotating rod 53. After the wafer loses the support of the rotating rod 53, it will fall on the side wall of the feed hopper of the jaw crusher and grinder, and slide downward along the side wall of the feed hopper of the jaw crusher and grinder to enter the feed port. Since the vertical distance between the end of the sliding rod 52 and the side wall of the feed hopper of the jaw crusher and grinder is less than the sum of the thicknesses of the two wafers, the wafers can only enter the feed port one by one, thus avoiding the accumulation of multiple wafers at the feed port.

[0050] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
